Mammography

Mammary ductography is a method of injecting a contrast agent into a breast duct to show a lesion of the catheter. Requirements for inspection: Checking for relaxation, checking may cause physical and psychological burdens, should be actively faced, and actively cooperate with the inspection. The examination needs to expose the breasts, so the upper body should wear clothes that are easy to take off. For patients with newly diagnosed breast diseases, if they are not satisfied with the physical examination, they can cooperate with the patients and check again at the best physical examination time, such as on the 10th day of the menstrual cycle to avoid physiological changes in the breast during the menstrual cycle. The interference caused. The examination should be adequately illuminated to avoid neglecting signs caused by minor lesions. Basic Information Specialist classification: gynecological examination classification: X-ray Applicable gender: whether women are fasting: not fasting Tips: Before the check: Check whether the contrast agent is allergic. Normal value The test result was negative. Clinical significance Abnormal results: The test result is positive: Intraductal papilloma: The angiography is characterized by a ductal shape, a smooth edge, and a filling defect. The proximal catheter often has an expansion and widening. Catheter dilation: manifested as the loss of normal dendritic morphology of each stage of the catheter, segmental widening or expansion into a saclike shape, in some cases due to a large number of secretions in the catheter, in addition to catheter widening changes can also be seen in the continuous irregular density reduction zone in the catheter, Make the edge of the catheter display not sharp. Mammary gland hyperplasia: clinically touched 10cm × 10cm mass, the catheters at all levels were evenly widened and extended, surrounded by small pressure around the mass, and several small cystic dilatations were seen at the end of the catheter. Fifteen patients with combined ductal dilatation also showed X-ray changes in catheter dilation. Breast abscess and mastitis: the contrast agent directly enters the abscess, the shape is irregular, the duct of the areola becomes thinner, the branch is reduced, and the edge of the catheter is blurred. Breast cancer: catheter angiography, X-ray angiography changes are not the same. Invasive ductal carcinoma: can be touched with a hard mass after the areola; the molybdenum target shows irregular mass, medium density and unevenness, and piles of sediment-like calcification in and around the mass, angiography sees the catheter interrupted in front of the mass, stump catheter Irregular damage and stiffness, no thickening of the catheter. The clinical contact with the hard and fixed mass: accompanied by bloody discharge; the molybdenum target showed uneven density of the mass, the edge was irregular, and the surrounding was seen to be thick and distorted. The angiography showed irregular destruction of the wall behind the main tube, and the wall was stiff and far. The small end of the catheter is slender, messy, and has a cluster-like distribution, which is collected on one side of the mass. People who need to be examined: the breasts touch people with lumps. Precautions Contraindications before examination: Check for allergies to the contrast agent. Requirements for inspection: Checking for relaxation, checking may cause physical and psychological burdens, should be actively faced, and actively cooperate with the inspection. The examination needs to expose the breasts, so the upper body should wear clothes that are easy to take off. For patients with newly diagnosed breast diseases, if they are not satisfied with the physical examination, they can cooperate with the patients and check again at the best physical examination time, such as on the 10th day of the menstrual cycle to avoid physiological changes in the breast during the menstrual cycle. The interference caused. The examination should be adequately illuminated to avoid neglecting signs caused by minor lesions. Inspection process Routine disinfection of the nipple, then squeeze the nipple to find the overflow catheter port, remove the secretion from the surface of the catheter, and slowly insert it into the milk duct 1~1.5cm with a 412-gauge needle (tip grinding), slowly inject 60%. Diatrizoate 0.5 ~ 3ml. Immediately after the needle is pulled out, one side of the lateral position and the axial position are taken, and no pressure or slight pressure is applied to prevent the contrast agent from overflowing. The exposure condition voltage can be slightly higher than the flat sheet. Not suitable for the crowd Inappropriate people: lactating women. Adverse reactions and risks No related complications and hazards were found.
